,This invention relates to a disk type of wheel especially adaptedfor'use in connection with motor vehicles, and especially that type ofvehicle employing a demountable tire, and being demounteble from the hubthereof.

The main feature of this invention is to so construct a disk wheelthatthe load will be carried thereb in' both compression and suspension,,and t e road shocks taken indirectly, tley shock being transmitted tothe axlewf the vehicle and distributed around the rim, 'the springtension inherent in the The construction of this disk- Ytype of wheel issuch that it will combine yielding qualities with @rengtl'i and affordmaximum resiliency.

"This is seeonpiiseeaby distingue disk' oulwardly and orming it of aneven thickness o sheetA metal, 1which will be yieldinglystrengthened'and braced by means of auxiliary disks of less diametermounted on eitherside of the supporting disk in position to 'engage andrace .against the supporting d' between .its center and periphery in thesame manner as the leaves of a -sprinvn f A iurther'advanta of thisconstruction lies in its ability to formed by a simple stamping processbecause of the even thickness of the sheet metal, whereas in most otherconstructions itis necessary to taper l the thickness thereof from thecenter outwardly to the periphery.

. A fuller advantage of the construction t ut herein, is the means forpreventing a y Vibration of the supporting disks, the vibration beingovercoine bythe yielding pressure exerted on each side thereof by thebracing auxiliary disks. 1

whereby as soon as their centralvportions are secured together as shownn Figlgs. A2 and 3 their peripheries will exert oppositely di'- rectedforces against the surface othe supporting disk 12 suiiicient tocounter-.act each other, and cause saidbracing disks 16 and 17 toimmediately take up any lateral stress or strain on the disk 12.

The three disks are secured together by riveting, and spacing them apartby the rings 22, sov that assembled, they form a single unit .formounting on the hub as shown inv Fig. 3. The assembled disks forming theWheel are removably secured on -the 'hub 13 by the nut 18 which securestheir centrall portion against the flanged portion of the hubs .13, thecollar l? and pins 20 retaining said disks in their proper relation Thenut 18 is further locked upon the hub by the locking nut 21 which screwsinto the inner threaded portion of the hub 13.

The invention claimed is:

1. A disk type wheel for vehicles including a hub, a supporting disksecured n n said hub composed of a single sheet of metal` a tire rimsecured to the periphery.

of said disk, and yielding bracing'means freely mounted adjacent eachside of said disk for resiliently bracing said disk against any stressor strain.

2. A disk type Wheel for vehicles including a hub, a supporting disksecured on said hub, and a disk mounted adjacent said supporting disk oneach side thereof and in free engagement therewith tor yieldinglyreinforcing said snpportinv disk against lateral or radial stress.

3. A disk type wheel for vehicles' including a hub, a supportii'ig disksecured on said hub, and a bracing disk mountedon each side o' andadjacent said supporting disk.

having its central portion spaced therefrom and its periphery in fleeengagement there- `with for yicldingly reinforcing said disk againstradial and lateral stress.

'i. A disk type wheel for vehicles including a hub, a supporting disksecured on said huh. said disk being (lished, a tire rim mounted on theperiphery of said disk, a bracing disk mounted on each side of saidsupporting disk and substantially conforming thereto so as to engage andreinforce said disk against lateral or radialvstress.

5. A disk type wheel for vehicles including a hub, a supporting disksecured on said hub, said disk being dished. and of equal thicknessthroughout, an inner reinforcing disk of lesser diameter andsubstantially conforming to said supporting disk having its centralportion spaced therefrom and its peripheral ledge in engagementtherewith, a reiunorcing disk mounted `on the outer side of saidsupporting` disk and of less diameter than said inner disk, and'havingits inner portion spaced from andits,

peripheral edge in engagement with said supporting disk whereby saidadjacent disks Will yieldingly reinforce said supporting disk againstradial and lateralV stress.

6. A disk type Wheel for vehicles including a hub, a supporting disksecured on said hub, said supporting disk beingdished outwardly, areinforcing disk mounted on each side'of said supporting disk forreinforcing it against radial and lateral stress, an inwardly turnedflanged portion about f the rperiphery of said supporting disk, and atire rim adapted to surround said fiange and be rigidly secured thereon.

7. A disk type wheel for vehicles including a hub, a supporting disksecured on said hub, and vresilient means for embracing said supportingdisk freely so as to counteract any lateral stress and overcome anyvibrations set up in said supporting disk.

8. A disk type wheel for vehicles including a hub, a supporting disksecured on said hub, and resilient disks so dished as' to be set upagainst opposite sides of said supporting disk under oppositely directedten-y sion whereby said supporting disk Will be firmly embraced andsupported against,

lateral strains. i
